Attack On Titan: Before The Fall Vol. 7

Written by Ryo Suzukaze with illustrations by Satoshi Shiki, Attack on Titan: Before the Fall is the manga adaptation of a series of light novels serving as a prequel to Hajime Isayama’s Attack on Titan.
The story is set 70 years before the original. It follows two stories: one focusing on Angel Aaltonen, the inventor of the Vertical Maneuvering Equipment used to fight Titans, and one focusing on Kuklo (the “Titan’s son”), a boy found in Titan vomit who goes on to join the Survey Corps.
Xavi Inocencio uses the tools of the Royal Government to find Kuklo and Sharle in volume 7! This volume includes chapters 21 through 24 and the extra "Swear Upon Wall Maria" in Japanese.
Notice: This manga is written in Japanese.
